This is just speculation, but Fall Guys has posted 4 silhouettes and the bottom right of the picture looks very familiar. Is Optimus Prime really coming to Fall Guys? https://twitter.com/FallGuysGame/status/1394623804366737413?s=19
I'm pretty sure it's Tron. The initial tweet mentions "light cycles" and the background of the image looks very Tron-ish.
I'm hoping that it's a transformers themed event since I have taken a long break and this would definitely get me back into playing it again.
